REGISTER OR GRILL.

Application filed December 10, 1919.

To all whom it may concern:

Be it known that I, EDWARD DAWSON HOWELL, a citizen of the United States of America, residing in S ringfield, Long Island, in the county of ueens and State of New York, have invented certain new and useful Improvements in Registers or Grills, of which the following is a specification.

This invention relates to improvements in registers or grills, or the like, and aims to provide improvements therein.

The present invention provides a register or grill which may be to a large extent formed of relatively light sheet metal, and which at the same time will have relative] great strength, enabling the register or gri l to bear considerable weights or loads when placed in floor openings.

This feature of strength provided by the present invention is of primary importance in registers or grills for large floor openings, such for example, as the openings used in conjunction with the so-called pipeless hot air furnace.

The invention further provides a rill or register structure which is of simp e construction and readily and cheaply manufactured.

The invention further provides a grill structure made in large part of sheet metal, which has the appearance of cast metal and the appearance of strength.

The invention further provides a register or grill formed in large part of sheetmetal, wherein much of the waste incidental to previous registers formed in part of sheet metal is eliminated.

The invention further provides a register or grill Work combining a maximum of strength with a maximum percentage of outlet space or openin The invention Ellthe! provides a construction formed in large part of sheet metal, wherein the necessity for reinforcement is to a large extent eliminated.

Other features of improvement will be hereinafter set forth.

An embodiment of the invention is illustrated in the accompanying drawings.

Figure 1 shows a top lan view of a grill or register, embodying t e invention, in the form in which it is used as a cover for a floor opening of relatively large size used in conjunction with the air pipe of a so-called pipeless furnace.

Specification of Letters Patent.

Patented Aug. 3, 1920.

Serial No. 343,868.

Fig. 2 is a sectional projection shown in Fig. 1, the section being on the line 2-2.

ig. 3 is a detailed view illustrating the joint between the cross bars.

In said drawings, numeral 1 designates a series of hollow strips; numeral 2 designates a series of cross strips, which are also preferably hollow- The strips 1 are preferably in the form of channel bars which are elongated in cross section, and in which the edges of the strips are bent inward toward one another, as indicated at 3. The strips 1 are most conveniently formed by rollin or bending from strips of sheet metal. lhe thickness of the sheet metal may be relatively small, sheet metal of No. 20 gage being satisfactorily employed for registers for oor openin s up to a relatively large size.

4 or receivin the cross strips 2, the strips 1 are providef with a seriesof notches 5, preferably dove-tailed, and preferably extendin inward from the closed side 7 .of the strips 1. The stri s l are made of considerable hei ht, an 7 the depth of the notches may 0, within the limits of good design, from one-third to one-half of the hei ht of the strips 1.

he cross strips 2 are preferably formed of sheet metal, and are in the form of channel bars, the strips 2 being inserted within the notches 5 of the' strips 1, having their sides 9 spread to fill out the notches 5. Pressure upon the notched side of the strips 1 causes the strips 2 to be gripped in the notches, the strips 1 and the cross strips 2 being by the construction described well interlocked.

The channel bars or cross strips 2 are preferably of a height corresponding to the depth of the notches 5, being thereby readily formed by rolling or bending a long narrow stri of sheet metal. The cross strips 2, if deslred, may be made of lighter metal than the strips 1. y

The closed sidesor faces of the strips 1 and 2 are referably flush upon the up er or outer sidia of the grill or register, so t at the said face of the register may be level. The flush upper sides 0 the strips also facilitate certain manufacturing 0 erations, such as the polishing of the face 0? the grill when the strips have'been coated or electro lated.

he grill may be fitted within a frame 15,

said first named series of this frame being referably formed of angle iron. A series of holes 16 may be provi ed in one of the webs of the angle iron, and the ends of the strips 1 and 2 fitted within these holes 16. In order that the strips 1 and 2 may be flush with the upper or outer face a 17 of the frame, the said ends of the strips are conveniently notched as indicated by the numeral 19. The ends of the strips 1 and 2, after passing through the holes 16, may be upset or spread so as to fasten them to the angle iron frame.

On the under side or inner side of the grill, where the grill is to be employed in conjunction with a ipeless furnace or the like, there is provided a collar 23 for making a slip joint With the air tube of the furnace. The collar 23 is preferably soldered to the strips 1 as indicated by numeral 25, and the collar 23, thus connected to the strips 1, serves as a reinforcement for the grill.

The grill is of relatively great strength, owing to the elongated shape or cross section of the strips 1. Moreover, by reason of the fitting of notches, a secure joint is made, which joint beclomes tighter the greater the load upon the gm 1.

The strips 1 and 2 of the grill, having considerable depth, present the appearance of strength and of cast metal. The strips 1 and 2, being narrow, provide, with a minimum weight of metal, a maximum outlet or opening therethrough.

As compared with grills or registers stamped out of a single sheet of sheet metal, the present grill may be made of very much thinner sheet metal, may be much stronger, and does away with much waste due to the cutting out of the openings from the sheet metal. Moreover, the reinforcement of sheet metal registers or grills is avoided by the present construction, except in the case of extremely large registers or grills.

The inventive ideas herein set forth may receive other embodiments than that herein specifically illustrated and described.

What I claim is 1. A register or grill for covering openings, comprising a series of hollow strips having notches strips seated in the notches in said first named series of strips.
